Remediation of wastewater using various nano-materials

Arabian Journal of Chemistry, Journal Year: 2016, Volume and Issue: 12(8), P. 4897 - 4919

Published: Oct. 19, 2016

In the present era of scarcity water resources, effective treatment wastewater is a major prerequisite for growing economy. It critical to develop and implement advanced technologies with high efficiency low capital requirement. Among various treatments, recent processes in nano-material sciences have been attracting attention scientists. However, limited collective knowledge available this context. The manuscript reviews potential developments nanotechnology respect treatment. article reviewed discussed utilization classes nano-materials processes. This includes four main classes; First, nano-adsorbents such as activated carbon, carbon nanotubes, grapheme, manganese oxide, zinc titanium magnesium oxide ferric oxides that are usually applied removal heavy metals from wastewater. Second, nano-catalysts photocatalyst, electrocatalyst, Fenton based catalyst, chemical oxidant shown removing both organic inorganic contaminants. Third, nano-membranes used dyes, foulants using nanotube membranes, electrospun nanofibers hybrid nano-membranes. Finally, integration biological algal membrane bioreactor, anaerobic digestion microbial fuel cell its purification.

A critical review on application of photocatalysis for toxicity reduction of real wastewaters

Journal of Cleaner Production, Journal Year: 2020, Volume and Issue: 258, P. 120694 - 120694

Published: Feb. 22, 2020

Advanced oxidation processes (AOPs) such as photocatalysis are widely studied for degradation of organic pollutants contaminants emerging concern (CECs). However, leads to formation by-products, which may be more toxic than parental contaminants. The toxicity wastewater treated by is topical issue. In this review paper recent studies concerned with photocatalytic detoxification real industrial and municipal were assembled critically discussed. Such issues challenges application detoxification, feasibility various tests, reuse photocatalysts, cost estimation, etc. considered. Based on reviewed literature it can suggested that might not always a promising treatment method in wastewaters and/or from the point view.

Designing Sites in Heterogeneous Catalysis: Are We Reaching Selectivities Competitive With Those of Homogeneous Catalysts?

Chemical Reviews, Journal Year: 2022, Volume and Issue: 122(9), P. 8594 - 8757

Published: March 3, 2022

A critical review of different prominent nanotechnologies adapted to catalysis is provided, with focus on how they contribute the improvement selectivity in heterogeneous catalysis. Ways modify catalytic sites range from use reversible or irreversible adsorption molecular modifiers immobilization tethering homogeneous catalysts and development well-defined solid surfaces. The latter covers methods for dispersion single-atom within supports as well complex nanostructures, it includes post-modification materials via processes such silylation atomic layer deposition. All these methodologies exhibit both advantages limitations, but all offer new avenues design specific applications. Because high cost most fact that resulting may limited thermal chemical stability, be best aimed at improving selective synthesis value-added chemicals, incorporated organic schemes, other applications are being explored address problems energy production, instance, greener processes. details each approaches discussed, representative examples provided. We conclude some general remarks future this field.
